About this app
Colour by Numbers is a permanent light installation in the tower at Telefonplan in Stockholm. With this app, you can change the colours of the light in the tower. The tower is 72 meters high and has 20 floors, of which the top ten are used for Colour by Numbers. The light installation is visible in many parts of Stockholm, within a radius of ten kilometers. Choose the floors that you want to colour by tapping on a floor or by swiping over the tower. You can deselect floors in the same way. Spin the colour wheels to colour the selected floors. You can create all colours by mixing red, green and blue. Share live images of the colours you create. www.colourbynumbers.org
